Magnetic Field Induced by Straight Currents on the Hyperboloid
Roman Krcmar, Andrej Gendiar, Tomotoshi Nishino
We consider the magnetic field induced by the steady or the quasi-steady electric currents that flow along the straight wires, which are equidistantly arranged on the hyperboloid.…

Tensor network calculation of boundary and corner magnetization
Roman Krcmar, Jozef Genzor, Andrej Gendiar +1
The Corner Transfer Matrix Renormalization Group (CTMRG) algorithm is modified to measure the magnetization at the boundary of the system, including the corners of the square-shape…

Vertex Representation of Hyperbolic Tensor Networks
Matej Mosko, Maria Polackova, Roman Krcmar +1
We propose a vertex representation of the tensor network (TN) for classical spin systems on hyperbolic lattices. The tensors form a network of regular -sided polygons () wi…
